Given numbers are 847, 209, 431, 149
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(847, 209) = 16093
GCD(847, 209) = ( 847 x 209 ) / 16093
= 847 / 209
= 847
Step2:
LCM(11, 431) = 4741
GCD(11, 431) = ( 11 x 431 ) / 4741
= 11 / 431
= 11
Step3:
LCM(1, 149) = 149
GCD(1, 149) = ( 1 x 149 ) / 149
= 1 / 149
= 1
So, Greatest Common Divisor of 847, 209, 431, 149 is 1
